I can't update Minecraft to 1.12, every time I press play with the 1.12 version, I get this error message:

I tried turning off my antivirus but it still doesn't work. Any ideas?

The process cannot access the file because it is being used by another process.

This probably means that you have 2 Minecraft launchers (or something similar) open at same time.

Here's some fix ideas:

• Close all of your Minecraft launchers and Minecrafts and try again.
• Log out (closing all of your open programs), log back in and try again.
• Restart your computer and try again.
• Delete your .minecraft folder. More info.

If you can't figure it out, Process Hacker can display apps using that file.

Shut down and restart your computer, then launch the client, go to launch options and make sure yours has C:/Users\USER\AppData\Roaming.minecraft for your game directory.

if you go to your .minecraft folder and go in to versions then delete everything in it then load minecraft 1.12.1 it should work.

the problem is the folder natives that probably do not download, It is a bug that can not be fixed, you can try download the version 1.12 from other computer and copy the folder of version 1.12 in your computer
